Overview:
This course engages students with little or no programming experience to create Java programs. Participants are introduced to object-oriented programming concepts, terminology,
and syntax, and the steps required to create basic Java programs using the Eclipse interactive development environments.
Course Objective:
- Learn the java concepts and different programming constructs and pass the "Java SE 8 Programmer I" Certification
Pre-requisite / Target Audience:
- Any beginner who wants to learn java and build career as a full stack developer can take this course.
Module 1: Java Basics
- Define the scope of variables
- Define the structure of a Java class
- Create executable Java applications with a main method; run a Java program from the command line; produce console output
- Import other Java packages to make them accessible in your code
- Compare and contrast the features and components of Java such as: platform independence, object orientation, encapsulation, etc.
Module 2: Using Operators and Decision Constructs
- Use Java operators; use parentheses to override operator precedence
- Test equality between Strings and other objects using == and equals ()
- Create if and if/else and ternary constructs
- se a switch statement
Module 3: Using Loop Constructs
- Create and use while loops
- Create and use for loops including the enhanced for loop
- Create and use do/while loops
- Compare loop constructs
- Use break and continue
Module 4: Working with Inheritance
- Describe inheritance and its benefits
- Develop code that makes use of polymorphism; develop code that overrides methods; differentiate between the type of a reference and the type of an object
- Determine when casting is necessary
- Use super and this to access objects and constructors
- Use abstract classes and interfaces
Module 5: Working with Selected classes from the Java API
- Manipulate data using the StringBuilder class and its methods
- Create and manipulate Strings
- Create and manipulate calendar data using classes from java.time.LocalDateTime, java.time.LocalDate, java.time.LocalTime, java.time.format.DateTimeFormatter, java.time.Period
- Declare and use an ArrayList of a given type
- Write a simple Lambda expression that consumes a Lambda Predicate expression
Module 6: Working With Java Data Types
- Declare and initialize variables (including casting of primitive data types)
- Differentiate between object reference variables and primitive variables
- Know how to read or write to object fields
- Explain an Object's Lifecycle (creation, "dereference by reassignment" and garbage collection)
- Develop code that uses wrapper classes such as Boolean, Double, and Integer Creating and Using Arrays
- Declare, instantiate, initialize and use a one-dimensional array
- Declare, instantiate, initialize and use multi-dimensional arrays
Module 7: Working with Methods and Encapsulation
- Create methods with arguments and return values, including overloaded methods
- Apply the static keyword to methods and fields
- Create and overload constructors; differentiate between default and user defined constructors
- Apply access modifiers
- Apply encapsulation principles to a class
- Determine the effect upon object references and primitive values when they are passed into methods that change the values
Module 8: Handling Exceptions
- Differentiate among checked exceptions, unchecked exceptions, and Errors
- Create a try-catch block and determine how exceptions alter normal program flow
- Describe the advantages of Exception handling
- Create and invoke a method that throws an exception
- Recognize common exception classes (such as NullPointerException, ArithmeticException, ArrayIndexOutOfBoundsException, ClassCastException)
